4-nin no Mama no Sei de Ore no Love Comedy ga Mama Naranai

Takumi, a high school boy living with his overly affectionate, beautiful stepmom and in love with his childhood friend, is at that age where romance blooms. One day, his stepmom mysteriously splits into four!? Each mom—yandere, tsundere, childish, and more—has her own unique personality and supports (or interferes with) Takumi's love life in her own way. A heartwarming (?) "mom-com" with four moms begins!
